There’s a divinity that shapes our blogs, rough-hew them how we will

Hello and good morning.  It’s Thursday, and as I promised‒or threatened, depending on your point of view‒here I am, writing my weekly blog post as before, back when I was regularly writing and publishing my fiction.

I’m not sure what topic(s) I should cover here, today.  I rarely seem able to plan these posts in advance, and when I do plan them, I don’t think they often come out very well.  That’s from my point of view, of course; maybe other people have found my planned posts excellent and wish I would write them more often, but if so, they haven’t given any clear feedback.  So, I don’t really know what will happen from now until the end of this blog post.

Of course, if the universe is deterministic, then whether I or anyone else knows it or not, what I will write is already a certain thing, as is the fact that I don’t know it‒indeed one could legitimately claim that it “already” exists in a sense, particularly if one is invoking the picture of Special and General Relativity and the “block” spacetime concept.

However, the Copenhagen interpretation (if that’s the correct term) of quantum mechanics states that wave-function collapse is truly “random”, and so the future is not determined, at least at the smallest level.  But if the wave function truly collapses, then that would be the only fundamentally irreversible temporal process known in physics so far, and that seems suspicious to me.

I’ve been reading the original EPR paper and thinking about this subject at least a little bit lately.

Of course, in a way, the Everettian “many worlds” interpretation of quantum mechanics would say that the future really is determined, but that at every instance of decoherence, the wavefunction becomes subdivided into waves that no longer interact with each other directly.  People interpret this as if new universes were coming into existence each time, and that’s a decent way to conceptualize it, but to me it seems misleading.

To my mind, it’s just waves that are traveling along in “parallel” and not influencing each other.  But that’s not really any different from the sounds of two separate conversations happening in a crowded room‒maybe one involves a group of people discussing a recent sporting event and another gaggle is talking about some new show on Netflix.  Maybe the conversations are even in different languages.  The sound waves propagate from each conversation independently, and though there may be places where troughs and crests pass and add or subtract for an instant, locally, they are very much different processes.  But there is no mystical invocation of “new universes” such as what troubles some people about Everettian quantum mechanics because of a misunderstanding of Occam’s Razor.  There are just separate, “parallel” things happening within the same overall universe.

That’s not a perfect analogy, of course.  The “waves” of the quantum mechanics are more complex* than sound waves, and are more fundamental, and once they decohere, it seems they are far less likely to interact with their other “branches” than are even sound waves of parallel conversations in different languages.  But even those are more separable than we think.

We have an exquisitely evolved capacity to parse the information out of human conversation, decoding the waves without thought, and so we don’t think very often about how astonishing that process is.  If aliens who communicated only by light flashes were trying to interpret such a set of conversations, they would have a daunting task, indeed.

Just think about how hard it has been even to decode the communications of dolphins and whales‒highly intelligent and social creatures that clearly communicate with each other.  And these are our fellow mammals from the same planet, who also use sound for communication!  We vastly underestimate the complexity of what we’re doing when we understand conversation and other noises, because our auditory processing systems do it without our conscious intervention, and they have been honed over hundreds of millions of years by the brutal and pitiless sieve** of natural selection.

Likewise, we thoroughly underestimate the complexity involved in catching a pop-up fly ball, or a thrown football, or the process of walking, or of throwing a ball, or of finding a specific item on a cluttered desk.  It shouldn’t surprise us that even if the future “division” of the universal wave function seems random, it can be utterly deterministic, and in that sense each branch “already” exists.  But each “branch” that no longer interacts with others after an instance of decoherence will “feel” to given humans*** as if it were the one and only “universe” and that all others have collapsed out of existence somehow, when they’re really just there but not interacting anymore with the person in question.

Maybe I’m wrong, of course.  I mean, I’ve been right before, but not often enough to make it my default presumption.

Anyway, there you have it, the stuff about which I was “destined” to write, though I had no specific plans.  That’s fair enough.  “Life is what happens while you’re making other plans,” as the saying goes.

Speaking of plans, though, I plan to write tomorrow and Saturday**** on my fiction (probably just on Extra Body).  I may take my laptop with me to do it; the experiment with my smartphone seems to be working okay (see my reports from Monday, Tuesday, and Wednesday), but it doesn’t feel quite as “natural” to me, still.  Who knows, though?

Only Laplace’s Demon® (Quantum Version™) knows.  But of course, that entity would feel, if anything, less “free” than those of us who know not yet what is to be and know not fully what has been.  For an entity that can see every detail of the past and the future laid out deterministically and in full detail is utterly incapable of taking any action on such knowledge‒for its own actions are as determined as all others, and it “knows” this.  Indeed, it cannot but know it.

Ignorance is not bliss, but it does at least give you room to improve, and that can be ego syntonic.

Have a good week, if such is your destiny.

*Ha ha, that’s a little physics joke there, when you think of how quantum wave functions involve complex numbers.

**Mixed metaphor alert!  How would a sieve hone anything?  Oh, well, I’m not going to change it; it works too well to communicate my meaning.

***And the very process of “feeling like something” is extraordinarily complex, and we only really understand the bare rudiments of how this happens.  This relative ignorance engenders the propagation of nonsensical, conceptually vacuous ideas like panpsychism and the like, and the pseudo-mystery of the “hard problem” of consciousness.  Well, it is a hard problem in a sense, but not the way philosophers of consciousness seem to express it, as far as I can see.

****I think I will be working Saturday, but I’m not certain, because of the highly atypical thing that happened last Saturday, with the office being closed.  This coming Saturday will be my son’s 24th birthday, and I will now literally have missed half of his life more or less completely.  That’s his preference, not mine, though it started as a consequence of my own misadventures‒our personal wavefunction decoherence if you will.  Still, when enough people repeatedly decide they don’t really like having you around or interacting with you too much, you have to think there must be some powerful causes for the consistency, especially when you don’t even really want to be around yourself.  So, I am profoundly sad about the state of things, and I miss my children terribly, but I have to conclude provisionally that they’re making a reasonable decision.  At least I “talk” to my daughter from time to time, and that’s not a small consolation.

Chaos surfing and the omni-curious mind

It’s Saturday morning and‒as I warned you‒I am writing a blog post today.

I just experienced a tiny little frisson of déjà vu, which is always interesting when it happens.  It involved that seemingly obvious, curious sensation that I could remember dreaming about the process of writing this particular blog post, in the location in which I’m writing it, at some time in the past.  Of course, I have no reason to suspect that precognitive dreams are actual things, except occasionally, by coincidence, due to the large number of dreams that happen and the brain’s capacity to model/predict its world with decent accuracy due to the regularities therein.  But déjà vu is still an interesting and sometimes enjoyable experience.

In case you haven’t noticed, mine is very much a stream-of-consciousness kind of blog.  I sometimes wish I were writing something more useful or informative or thought-provoking.  Then I could imagine I was contributing to the world in some way.  I have a wide range of knowledge on lots of topics‒science in general, some physics and cosmology, biology and medicine, some mathematics, a tiny bit of computers, and of course some philosophy (and psychology).

I sometimes regret not having explored philosophy more at an earlier age.  There was a philosophy class in my high school; it was one of my favorite classes, and the teacher was great, but I avoided philosophy in college deliberately.  I had little understanding of how good and useful it‒as well as pure mathematics, not solely for use in physics‒is in improving one’s ability to think about all subjects.

At its “worst” it’s at least analogous to doing calisthenics to get stronger and more fit.  One doesn’t do push ups in order to become a world champion at push ups‒usually‒and one doesn’t do push ups because one expects to become a professional pusher up and to make one’s living that way.  As far as I know, there is no such profession.  One does it to keep one’s body fit so it is more capable of responding to any of a functionally limitless number of specific challenges throughout life.  So it is with the mind, but the mind is far more capable of growth and strengthening than even the greatest athlete’s body has ever been.

I get so frustrated when I hear people whining about, say, the fact that they never use the Pythagorean Theorem in their daily lives, or haven’t used algebra since they left school.  My first reaction when I hear such moans is to think, “If that’s true, then too bad for you; you’re missing out.”

But I also find it noteworthy that most people don’t complain of the fact that they’ve never played kickball or tag or used their sandlot baseball skills in their later life.  Similarly, very few people get jobs playing video games‒there is a vanishingly small few who make at least temporary livings playing video games competitively, but that’s not a reliable long-term strategy for almost anyone.  Such skills are, for the most part, far less useful than those of algebra and calculus‒though I understand that there is some evidence that playing video games can make people better drivers by improving their alertness and response times.

Breadth and depth of knowledge are ends in themselves; they are their own reward, one might say.  When one learns something new, one makes oneself “larger” without taking anything away from anyone else*.  Information can be shared without loss, and one can contain whole universes‒real and/or imaginary‒in one’s mind.  It’s remarkable.

But also, knowledge, even of esoterica, is of practical, basic value.  Insights gained from having studied epistemology or Boolean logic may become useful, unexpectedly, in a business negotiation or a plumbing emergency.  Who knows?  The world is too complex for one to be able to predict the specifics of local events very far ahead of time‒and even the precise knowledge of that fact is based on an originally obscure branch of mathematics and information theory, and was formally born of the use of a “primitive” computer weather simulation.

You cannot fundamentally alter the chaotic nature of reality.  You cannot effectively steer the chaos‒but you can learn to surf on it.  And the more you know and the greater the breadth of your mental skills, the more likely you are to be able to catch the right waves and ride them to someplace you’d like to be.

Anyway, back to what I was saying earlier:  I sometimes imagine myself doing a more informative or exploratory blog, a discussion of sorts, albeit one-sided.  When I leave it to my stream of consciousness, my blog is often depressing (or at least it’s often depressed).  But I don’t know what people might like to read my thinking about; I have a great deal of difficulty understanding what other people find interesting or engaging, let alone why.  So, if anyone has any general subjects they’d like me to explore, whether truly broad or regarding current events or science news or anything within my relative wheelhouse**, feel free to let me know in the comments…or, I suppose, via Facebook or Twitter.  I don’t like to encourage such things, but these “social media” can be entertaining and even useful in certain rarefied situations.

In the meantime, have a good weekend if you’re able to do so.

*Apart from the tiny, tiny increase in overall universal entropy that all learning entails.  But that’s going to happen anyway, and the entropy created by a lifetime of astonishing erudition is unnoticeably small next to, say, that produced every day simply by the Earth absorbing sunlight, warming up, and releasing higher-entropy heat back out into the cosmos.

**My wheelhouse walls are made of rice paper, so I can easily knock them down and expand that chamber as desired.  I dream of my wheelhouse eventually being as large as the cosmic horizon‒or even larger!  Why not?

There may be no firm fundament but is there a fun firmament?

It’s Tuesday morning, now, and I’m writing this on my laptop computer, mainly to spare my thumbs, but also because I just prefer real typing to the constrictive and error-ridden twiddling of virtual buttons on a very small phone screen.

Speaking of the day, if the Beatles song Lady Madonna is correct, then it’s still Tuesday afternoon, and has been at least since last Tuesday, since “Tuesday afternoon is never-ending”.  Of course, if Tuesday afternoon really is never-ending, then it has been Tuesday afternoon ever since the first Tuesday afternoon.  From a certain point of view, this is trivially the case.  After all, every moment after 12pm on the first Tuesday that ever happened could be considered Tuesday afternoon—or, at least, they could be considered “after Tuesday noon” if you will.

Enough of that particular nonsense.  I only wrote that because there’s nothing sensible about which to write that comes to my mind.  But, of course, in a larger sense, there is nothing “sensible” at all.

There are things that can be sensed, obviously.  I can see, hear, and touch this computer, for instance.  If I wanted, I could probably smell it, though I think its odor is likely quite subdued.  But I mean “sensible” in the more colloquial, bastardized, mutated sense—as in the word “sense” just there—which has to do with something being logical, reasonable, rational, coherent, that sort of thing.  Indeed, it has to do with things having meaning.

Deep down, though, from the telos point of view, there is no true, inherent meaning to much of anything, as far as anyone can see.  Certainly there’s no meaning that anyone has ever demonstrated or asserted convincingly that I have encountered at any point in my life.

Of course, people have beliefs and they have convictions, and humans assign meanings to various things.  All the words I have used in writing this post so far, and all the words I will use henceforth, have “meanings”, but those are invented meanings.  There is nothing in the collection of letters—nor indeed in the shapes of the letters themselves, nor the way we put them down on paper or a screen—that means anything intrinsically.  They were all invented, like justice and morality and the whole lot of such things.

That something is invented doesn’t mean it isn’t real, of course.  Cars are an invention, and only a fool (in the modern world) would deny that cars are real.  But they are not inherent to the universe; they are not in any sense fundamental.

In a related sense, even DNA and the protein structures for which it codes are very much not fundamental; they are quasi-arbitrary.  Of course, one cannot make DNA or RNA or proteins out of substrates for which the chemistry simply will not hold together.  But the genetic code—the set of three-nucleotide-long “letters”, the codons, in the genetic code that each associate with a given amino acid (or a stop signal, or similar) as they are transcribed into proteins—is arbitrary.  There’s nothing inherent in any set of three nucleotides that makes it associate with some particular amino acid.

This sort of thing took me quite a long time to realize as I was growing up and trying to understand biology and chemistry and such.  What, for instance, was the chemical reaction with, say, adrenaline that made things in the body speed up and go into “fight or flight” mode, as it were?  How was it that aspirin chemically interacted with bodies and nervous systems to blunt pain?  How many possible chemical reactions were there, really?  It was mind-boggling that there could be so many reactions, and that they could all produce such disparate effects on various creatures.

When finally I was shown the real nature of such things, it was definitely a scales-dropping-from-eyes moment.  There is nothing inherent in the chemistry of DNA, or of drugs or hormones, that produces their effects.  There is no inherent “soporific” quality to an anesthetic.  You could give a dose of Versed  that would kill a human to some alien with a different biology, and at most its effects would be those of a contaminant.

It’s all just a kind of language—indeed, it’s almost a kind of computer language, and hormones are just messengers*, which are more or less arbitrary, like the ASCII code for representing characters within computer systems.  Likewise, there’s nothing in the word “cat” that has direct connection with the animal to which it refers.  It’s just keyed to that creature in our minds, arbitrarily, as is demonstrated by the fact that, for instance, in Japan the term is “neko” (or, well, it sounds like that—the actual written term is ねこ or 猫).

Of course, there are things in the universe that, as far as we can tell, are fundamental, such as quantum fields and gravity and spacetime itself.  But even these may yet peel away and be revealed to be arbitrary or semi-arbitrary forms of some other, deeper, underlying unity, as is postulated in string theory, for instance.

The specific forms of the fundamental particles and forces in our universe may—if string theory and eternal inflationary cosmology for instance are correct—be just one possible version of a potential 10500 or more** possible sets of particles and forces determined by the particular Calabi-Yau “shape” and configuration of the curled up extra dimensions of space that string theory hypothesizes.  So, the very fundamental forces of nature, or at least the “constants” thereof, may be arbitrary—historical accidents, as much as are the forms and specifics of the life that currently exists on Earth.

And what’s to say that strings and branes and Calabi-Yau manifolds are fundamental, either?  Perhaps reality has no fundament whatsoever.  Perhaps it is a bottomless pit of meaninglessness, in which only truly fundamental mathematics are consistent throughout…if even they are.

I’m not likely to arrive at a conclusion regarding these matters in a blog post written off-the-cuff in the morning while commuting to the office.  But I guess it all supports a would-be Stoic philosophical ideal, which urges us to let go of things that are outside our control and instead try to focus on those things over which we have some power:  our thoughts and our actions.

Of course, even these are, at some deeper level, not truly or at least not fully ours to control—we cannot affect the past that led to our present state, after all, and the future is born of that present which is born of that past over which we have no control.  But, for practical purposes, the levers that we use to control ourselves are the only levers we have to use.

We might as well keep a grip on them as well as we can, and not worry too much about things that are not in our current reach.  Though we can try to stretch out and limber up, maybe practice some mental yoga, to try to extend that reach over time, I suppose.  But that’s a subject for some other blog post, I guess; this one has already gone on long enough.

*For the most part.  Things like cholesterol and fatty acids and sugars—and certainly water and oxygen—and other fundamental building blocks do have inherent chemical properties that make them useful for the purposes to which bodies put them.  Then again, words can have tendencies that make them more useful for some things than others, too.  “No” and “yes” are short and clear and clearly different sounds, for instance; it makes sense that such words evolved to be such important, fundamentally dichotomous signals.

**That means 10 x 10 x 10 x 10… until you’ve done that multiplication 500 times.  You may know that a “googol” is a mere 10100, and that in itself is already roughly 20 orders of magnitude (100,000,000,000,000,000,000 times!) larger than the number of protons and neutrons estimated to exist in the visible universe.  So 10500 is a number far vaster than could ever be written out within the confines of the universe that we can ever see.  There’s not enough space, let alone enough matter, with which to write it.  It’s a googol times a googol times a googol times a googol times a googol!

Don’t be afraid of “scare quotes”; they are–as am I–here to “help”

It’s Friday at last, the last day of a work week that has lasted at least 12 days already (subjectively speaking).  I am not working tomorrow, so there will be no blog post made again until Monday, barring‒as must always be the case‒the unforeseen.

I will try to remember to send myself the audio files for my last two audio blogs‒or perhaps it was three‒to turn into “videos” over the weekend.  I haven’t downloaded clipchamp or whatever it is to my home computer, but it should be no more difficult to do there than it was at work.  Of course, I may not do that, so don’t make any plans that depend upon my doing it‒goodness knows what such plans might be.

I’m not sure if anyone really likes those “video” versions of my audio blogs or is just as happy with the plain audio.  I’ve noted before that storage on YouTube is functionally limitless (as opposed to WordPress) but if I’m loading them here first, anyway, that’s a moot point at best.

You may have noticed that I tend to put quotation marks around the word “video” when I refer to the above, because though technically they are indeed video files, the visual portion is just a static image.  I’m a big fan of so-called scare quotes.  I think we should use them far more often than we do.  People often arrogate terms to themselves, or use epithets against others, as a means of manipulation, as if invoking some sequence of letters or sounds causes a thing actually to be the case, and I think it’s important to point out when one is unconvinced that the term is being used properly or accurately.

Perhaps the most prominent and pointed such ill-use might be regarding “progressives” and “conservatives”.  Both groups inherited the terms from people who came before, and who perhaps more accurately embodied the general meanings of the words, but they are now simply camouflage uniforms, at least in many cases.  You can call yourself a “freedom fighter” if you want, but using that term doesn’t mean you’re not a terrorist or that you’re actually interested in any legitimate form of freedom.

Of course, real conservatives and progressives being at hostile odds with one another doesn’t make much sense if one is considering the usual meanings of the terms rather than claiming them as team names in some tribal contest of primate dominance.  It makes sense to conserve those things in a society that are effective, that have been tested by time and found to be useful, but it’s just as reasonable that everyone should want to make actual progress whenever possible, to improve life and prosperity for everyone as much as is feasible.

The real, useful discussion would be about which things are working well and should be conserved, and which things require improvement and how to go about it.  There will be substantial disagreement on such questions, of course, and part of the discussion must always be how to decide what best to keep as it is and what is the most fruitful area in which to improve things

People of good will‒who do not think in terms of “us” versus “them” but in terms of usefulness and effectiveness and trying to get the best outcome for as big an “us” as possible‒can work in ways that will be beneficial by whatever measures one might want to use, keeping in mind always that all conclusions are in principle provisional and all processes and people are fallible, but that all problems are in principal soluble.

I’m not sure humans are clever enough primates to achieve such matters for long.  They seem to devolve so readily into conflicting tribes.  I guess this makes sense given the ancestral environment, with groups of only on the order of perhaps about 150 people living together.  But there’s no good excuse for not recognizing that tribal modes cannot function ideally in a setting in which 8 billion people are interacting in a massive and incredibly productive and complex economy and polity.  At higher levels of complexity, newer “rules” are going to tend to be required.

Humans aren’t necessarily all that good at adjusting to such things, though.  I often think that it will require a new and ongoing external threat, such as a supervillain or an alien invasion, to bring humanity together in total.  I’ve often been tempted to volunteer myself for the position, since humanity really can be contemptible and infuriating to me.

It’s not that humans are worse than the other life forms on Earth; I don’t think they are.  Life in general is frequently vicious and cruel and wretched, with all living things riding the knife edge of death and extinction much, perhaps most, of the time.  Nature’s equilibria are not achieved by some beautiful, fairy tale cooperation and self-restraint between forest creatures or what have you.  Equilibria are maintained by disease and death, by starvation and predation.  Agent Smith was just wrong, dead wrong, in his assessment of life’s tendency to form such natural equilibria.  He was too generous in his assessment of non-human forms of life.

Humans, however, are more competent than other animals.  They are also the only ones even capable of seriously planning ahead to strike a flexible and ever-changing balance between conservatism and progress.  It’s that they so often fail even to try to rise above their lizard-monkey minds that is so infuriating, and they themselves are among the worst of their victims.

Sometimes I think just wiping them all out would be a kindness‒not to the rest of the living world, which is certainly no more admirable or worthy of kindness than humans, but to humans themselves.  After all, if a function in time is always negative, then integrating the area “under” the curve will always yield a negative, and a permanent regression to zero would be a gain.  Maybe the universe, or at least the Earth, would be kinder in aggregate if it were sterile.

It’s food for thought, at least, and it is tempting.  What do you all think?  I’m not asking what you feel.  I hate feelings*.  But when you are as close to dispassionate and disinterested as you can make yourself, what do you think?  Does the human race (and by reflection, life itself) require an enemy to bring out its best?  If so, does it not then “deserve” that enemy?  And if it cannot defeat that enemy, does it not “deserve” to be destroyed?

I suspect that might be the case.

*Ha ha, that’s a little joke.

Morgoth, Arda, redemption, morality, and blame (not the name of a law firm)

I was out sick yesterday, but the following is audio I recorded this morning about ideas of redemption and recreation in the world of J.R.R. Tolkien, especially as goes for beings and characters such as Melkor/Morgoth and Sauron and the like.  It’s a bit meandering, I fear, and it’s longer than other recent stuff has been, but please let me know if you find it interesting, and if you have any comments on the subject(s), or on such audio posts in general, I would be glad to receive your feedback. I’ll probably be turning it into a “video” eventually, for YouTube.  I don’t know, are those easier to partake of than the audio here on the blog?  Certainly the storage availability on YouTube is functionally unlimited, but I’m not yet anywhere near the limits of my personal storage here on WordPress yet, anyway.

This probably almost would count as a podcast, though I don’t know whether I feel comfortable arrogating that status to my measly ponderings.

Let me know what you think, please, and thank you.

Addendum:  Here is the link to In Deep Geek.  

I also highly recommend Nerd of the Rings.

Causality, relativity, uncertainty, and attractive versus repulsive gravity–these are worth celebrating

Okay, well, I’m writing this blog post from the office, because this is where I slept last night after the holiday party.  We did not have the party at the office, just to be clear.  We had it at a very decent restaurant called Maggiano’s, which may be part of a chain to some extent, I think.  It was a nice enough restaurant, food-wise, and the building and the outside lights were quite beautiful (see below).  However, inside, it was way too crowded and noisy, and we were seated at a very long, narrow table against a wall.

I felt incredibly stressed when we first arrived; I can hardly hear out of my right ear for one, and I have had tinnitus in it since about 2007 or so, and everything else was a tumult and commotion.  There was too much visual sensory overload also, and way too many people in too close quarters.  I miss the social mores of the pandemic, honestly.  I was barely able to endure long enough for our server to get me a drink so I could calm down a little.  I almost left and just walked back to the office.

My difficulties with such things have gotten worse over time, probably at least partly because I only ever used to go to restaurants and whatnot with people with whom I felt quite comfortable—my family, near and extended, then my wife, her family, our family, and so on—so there was always someone on whom I could focus, and with whom I could speak.

The drinks were rather weak, which may be good, since it was a work night, but I had to drink several to keep from tensing up.  Even so, at the end of the night, when they wanted to take a big group photo, I just walked away.  I had been dodging pictures all night already; there was a terribly annoying number of them, because everyone has their own little cameras in their smartphones, so instead of conversation—which was very difficult with anyone more than one seat away, and pretty hard even with those neighbors—people just took their little, instant, digital snaps, which I suspect will never really be used for recalling memories.

I’ve said it before, it’s not the case that things on the internet (or smartphones or whatever) are forever, as is sometimes claimed.  There is such a cacophony of data and images and whatnot, a good portion of it now not even being “real”, that most things will be swiftly lost like a drop of ink in a roiling, stormy ocean, or the quantum information of something that’s fallen in a black hole.  In principle it’s all there, but in practice it’s as lost as the echoes of Julius Caesar’s death rattle.

I guess it was a pretty nice evening, and the food was pretty good.  The salad was above average, and the broccoli I had on the side with my ziti dish was good.  It was all certainly well above the level of, for instance, the Olive Garden, but it was terribly noisy, literally and figuratively.  By the end, when we were the last party in the restaurant, it was still noisy, because our group was terribly noisy, and it was embarrassing and unpleasant.

I think I mostly at least prevented anyone from capturing my disgusting current face and form on camera in anything other than, perhaps, an oblique angle.  I really don’t like how I look, or how I feel, and certainly don’t want it memorialized, even if it’s evanescent and ephemeral*.

After the party, I was brought back to the office, which is only about four miles from the restaurant.  I could have walked, since the night was reasonably cool, but since I knew I wouldn’t be taking a shower, I decided not to do that.  I have washed up this morning and applied antiperspirant and aftershave (or whatever you call it when you haven’t actually shaved) and I brushed my teeth and everything.  I slept on the floor, with my backpack as my pillow, and it was about as comfortable as sleeping at the house, and I got about 3 hours of sleep.

This is the state in which my life is and has been for years now:  sleeping at the office and spending time here (by myself) is just as pleasant as being at the place where I nominally live.  That’s because I have no life, and I don’t expect one to occur again for me.  I’m really absolutely dismal and morose and unpleasant, even to myself.

I’ve hardly even read anything in over three weeks now, which is very weird and rare for me.  The single thing to which I’m now looking forward is the Doctor Who Christmas special, and that’s not a huge draw, just a pleasant one.  It’s not as though I’m actually watching it with anyone or can talk about it with a friend or anything.

I got out the hardcover books Spacetime and Geometry and Quantum Field Theory, As Simply as Possible at the office.  I have them resting on the desk, hoping to entice myself during any downtime I might have at work.  So far it hasn’t paid off, but I would like to master the mathematics of GR well enough that I can understand intuitively why a uniform energy field permeating space generates “repulsive gravity”.  I understand that it does, but I don’t have a good picture of it in my head, whereas I do have a much clearer intuitive sense of why the curvature of spacetime (especially the time part) leads to the apparent force of attractive gravity.

In a way, that’s my only remaining unaccomplished (and reasonably achievable) goal.  Quantum field theory is interesting and all, but the basic concepts of it seem fairly straightforward to me**.  Contrary to what people often say, quantum mechanics (et al) are only really counter-intuitive if you insist upon trying to apply macroscopic and mesoscopic intuitions to phenomena that happen at much smaller scales.  It’s a bit like expecting one of your bathroom tiles to behave just like the Burj Khalifa, only the scale is much more disparate between the quantum and the macroscopic.

People seem somehow puzzled by the notion of how complementary pairs of one’s measurements of quantum “particles” can never be more accurate than a certain level, as if this is truly different from measurements of macroscopic phenomena.  I’m quite sure that the errors when measuring, say, the mass or velocity of something as large as an elephant, or a car, or what have you, are waaaaaay huger than the absolute uncertainty in measurement of the position and/or momentum of a particle.  They’re just not as noticeable because the thing itself is big, and so the percentage of the error might be smaller and less consequential.

But we know things change with scale, like surface to volume ratios and whatnot.  An uncertainty of a millimeter when measuring a blue whale is hardly relevant, but if you’re measuring an ant, it could easily be crucial, and if you’re measuring a dust mite that error would be larger than the organism.

I also don’t get the objection to the possible “many worlds” description of quantum mechanics that derives from the fact that we only ever see and experience one world.  I don’t know why that puzzles people.  It’s not as if you can see both the outside and the inside of all the solid objects around you.  If you touch the near surface of a basketball with one finger, you can’t feel the opposite side of the ball with the same finger at the same time.

Yet, there’s no real doubt that the inside and the other side of physical objects really exist.  We just can’t sense the whole of any given thing at once.  Any part of space that will never enter our future light cones is something we will never, ever see at all***, but we don’t have any good reason to doubt that far distant regions of spacetime exist.  Internal consistency of reality and logical coherence of the world seem to demand many things existing with which we will not, and sometimes cannot, ever interact.

Okay, that was a weird tangent.  My apologies.  Anyway, I doubt that I’m going to achieve my “dream” of getting an intuitive, mathematical understanding, something I can feel, about why spacetime expands in the presence of a uniform energy.  After all, it’s something about which I honestly care, and my track record with such things is abysmal.  I don’t expect to achieve anything else of value, even to me, in my life.

I’m tired, I’m sad, I’m depressed, I’m alone; the only person in whose presence I always find myself is a person I despise (me).  My catharsis via this blog isn’t working.  I’m getting no help, though I wish for it, but I’m not sure how well I would respond if some were to come.  Maybe, like the wonderful simile Sting used in Be Still My Beating Heart, I would wriggle like a fish caught on dry land, unable to tell the difference between help and danger, between an offer of comfort and a warning of pain.

Whatever.  Sorry, that’s all pathetic, isn’t it?

In closing, I wonder if anyone listened to my little audio snippet yesterday, and if anyone thought it was worth it for me to try to do such a thing more often.  Let me know in the comments (on WordPress) if you have any feedback to offer.  Thanks.

*Performing together live, for the first time.

**Straightforward for quantum field theory type things, anyway, to be fair.  I don’t mean that it’s not complex (ha ha! it uses complex numbers all the time, get it?) but I have a sort of picture of how the processes work, and it makes sense.  The rest would just be building details and specifics on top of the basic framework, which is a lot, of course, but there’s no real intellectual hurdle to be cleared.

***Assuming we do not discover any exceptions or workarounds to special relativity and the speed-of-causality limit.  There could in principle be workarounds, but it seems unlikely that there are local exceptions to the cosmic speed limit.  In any case, even such exceptions shouldn’t violate chains of causality.

Believing in “believing in” matters of empirical reality…or not

The other day, I was scrolling through The Website Formerly Known as Twitter—which I tend to do after sharing my blog posts there, since it seems the polite thing to do—and I saw a “tweet” or an “X-udate” or “X-cretion” or whatever one calls them now, that asked, “Do you believe in global warming?”

Such questions always seem bizarre to me.  It’s similar to the old, “Do you believe in UFOs?”  Though, with the latter, one can always snarkily reply, “Why, yes, I believe in unidentified flying objects.  I think people often see things in the sky that they cannot properly identify, especially if they are not experts and conditions are not ideal.”  But really, even that sarcastic response misses the point and can be misleading, so it’s best to be avoided.

The problem is, the question entails a kind of category error.  The reality of global warming—by which I assume the questioner means some form of anthropogenic climate change—is an empirical question.  It is a statement about reality itself, and is either true or false whether or not anyone even knows about it as a possibility, let alone “believes in it”.

It’s more reasonable to ask, “Do you believe that anthropogenic climate change—AKA global warming—is happening?”  That, at least, is a sensible question, when using the form of the word “belief” that means that, based on the evidence and reasoning one has available, one has arrived at the provisional conclusion that global warming is happening (or is not).

In using this term “belief”, one would usually imply that one is reasonably convinced, but open in principle to alternative explanations and counter arguments and new evidence—as one always should be in matters of empirical fact, at least if one is committed to always trying to make one’s map describe the territory as well as possible (to borrow a phrase from Eliezer Yudkowsky).

But when people say, “Do you believe in…” something, it doesn’t come across—to me at least—like a question about facts, but rather as a question about ideologies, about team membership, about religion, in a way.  It can be at least excusable and appropriate, if still rather nonsensical in my view, to ask someone if they believe in Santa Claus, or in Communism, or in God.  It doesn’t necessarily have anything to do with external reality other than the state of certain people’s minds, but at least it’s reasonably appropriate.

The absurdity of this conflation of “believing in” something with an assessment of a thing’s actual reality is pointed out well in Terry Pratchett’s delightful Discworld novels—in either Wyrd Sisters or Witches Abroad, if memory serves.  I don’t recall how the point comes up, but it relates to belief in the gods of Discworld.  The narration says that, of course, witches knew that the gods were real, they had dealings with them, they sometimes met them.  But that didn’t mean there was any call to go believing in them.  It would be like believing in the postman.

If someone were to ask me whether I think that climate change is real, and why I think whatever I think, I might reply that the general consensus of the world’s climate scientists—people who actually specialize in the area—seems to be that it is happening, and though their most specific predictions can be highly uncertain, as can all specific predictions in science beyond the realms of simple linear dynamics, most of them conclude that it is really happening.

I read a statement once that claimed that the percentage of climate scientists who are convinced that human-caused global warming is really happening is higher than the percentage of medical scientists who are convinced that smoking tobacco increases the risk of lung cancer.  I don’t know whether that statement is true, and I don’t recall the source—it sounds more like a rhetorical point than an actual argument, which makes me suspicious.  If it is true, it’s remarkable in more than one direction.

One can look up in journals the papers and the data that is being gathered and analyzed by climate scientists.  Google Scholar works nicely for searching out real, published scientific studies on almost any amendable topic.  One can also go to pre-print servers such as arXiv, to see papers that have not yet been peer reviewed.

If one is judicious, one can even find decent science news in less technical publications—phys.org seems to be pretty good—but mainstream reporting on such things is often unreliable and inconsistent, since after all mainstream media exist primarily to sell themselves, not necessarily to promulgate the most rigorous truth they can uncover.  Even Scientific American has turned into a twisted mockery of its former self.

I understand at least some of the physics behind the “greenhouse effect”, without which the Earth would be uninhabitably cold.  Visible light passes through the atmosphere without interacting much with the gases therein—which is why air is mostly transparent, other than the modest scattering of blue light that leads to the sky’s daytime color (and inversely to the color of sunsets).  But such relatively low-entropy, high frequency light is absorbed by the ground, then reemitted as higher entropy, lower frequency light, such as infrared, which is much more readily absorbed by molecules like CO2 and H2O and methane (CH4).  The reasons for this are quantum mechanical in nature, but the fact that it happens is basic physics that’s been well known since before anyone currently alive was born, as far as I know.

And so, these atmospheric gases heat up (and in turn heat up the other atmospheric gases) until the outer surface of the atmosphere is warm enough to radiate out as much energy as comes into the Earth.  Such is the nature of so-called black body radiation.

But for the outer atmosphere to be warm enough to do this, the middle atmosphere must be warmer, and the layer below warmer still, and so on, since outer layers radiate inward as well as outward.  The outer layer of the atmosphere will always be just warm enough to radiate out just as much energy as the Earth receives in light from the sun; if it were not, the Earth would rapidly get hotter until a new equilibrium was reached.  The final radiating surface might end up being higher in the atmosphere, which would mean that, closer to the surface, things would be warmer.

Anyone who has dressed in layers in cold weather should understand this intuitively.

[By the way, there may be some slight imprecisions in my very quick summary above of the thermodynamics of atmospheric gases, so if any experts in the matter would like to make any corrections—especially if such corrections are truly substantive—please feel free to do so in the comments.]

There are other atmospheric effects that are even easier to understand at basic chemical levels, such as the fact that increasing CO2  concentration leads to increasing acidification of the oceans.  This is fairly straightforward chemistry—carbon dioxide, when dissolved in water, partially reacts to form a weak acid—“weak” meaning just that the hydrogen ions do not completely dissociate from the molecule H2CO3*.  This can be demonstrated easily by getting some pH paper (readily available at all high street pH paper shops), testing some neutral water (to confirm its baseline neutral pH) and then blowing through a straw into the water for a few minutes.  You can then check if the pH has dropped, which—if you are a typical mammalian creature from Earth—it will have done.

I think this experiment can also be done with phenolphthalein, which is wine-red when in a basic (alkaline) solution and clear when in an acidic environment.  You can do a sort of magic trick, turning “wine” into “water” with just your breath through a straw bubbling in a glass.  Don’t drink it, though.  I don’t think phenolphthalein is particularly dangerous, but I wouldn’t want to endorse someone imbibing it.

I’m not going to tell you my conclusions about the empirical fact of whether or not “global warming” is happening and how and why and all that.  You can explore the subject as a homework assignment (but don’t hand it in to me).  But I will tell you my conclusion, which is probably obvious, about “believing in” things.  I don’t believe in “global warming” nor in the lack thereof.  I don’t believe in Santa Claus.  I don’t believe in Capitalism or Communism or Socialism or Fascism or Scientism** or Antidisestablishmentarianism.  I don’t believe in the Tooth Fairy, and I don’t believe in life after love.

And I really don’t believe it’s useful or good or anything but an irrationality to “believe in” matters that involve claims about the nature of reality itself.  Reality is that which exists whether or not anyone believes in it—indeed, whether or not anyone exists to be capable of believing in it.  That’s why it’s reality, as opposed to fictions and ideologies and other abstract concepts of various kinds.

I know*** that Amazon delivery people exist.  That doesn’t mean there’s any call to go believing in them.

* H2O + CO2 ⇌ H2CO3 ⇌ H+ + HCO3–.  Something like that, anyway.

** Though I have more sympathy for Scientism than most “isms”.

***Not to a mathematical certainty, but to such a high degree that there’s no clear point in considering other possibilities, pending new evidence and/or arguments.

The Treatment Trap

In America today, we rely far too much on pills and on procedures–on would-be “cures” for our problems–than we really should.

It may seem strange for a medical doctor like me to be saying this, but I have insight into the issue from multiple perspectives.  I’ve been one of the doctors who falls into the trap of trying to “treat” every issue rather than prevent or solve it, and I’ve been a patient who approaches things the same way.

The irony is that a great many of the health problems we face in the modern world–especially the most rampant and devastating ones, such as diabetes, high blood pressure, heart disease and their related problems and consequences–are governable simply by modifying our lifestyles.  Indeed, for many of us, these health concerns’ very existence AS problems is only CAUSED by our modern lifestyles.  I’ve already discussed in some earlier entries the mechanisms and effects of type 2 diabetes, a disorder which is becoming more and more endemic in our nation, and at younger and younger ages.  It’s absolutely clear why this is happening:  We are more sedentary and more overweight and we eat more rapidly absorbed carbohydrates than humans have ever done before in our existence.  What’s more, thanks to public health interventions and control of infectious diseases, we live long enough for these habits to matter more than they could have in the past.  We also know, quite well, many of the things that we can do to counter diabetes and its close relatives, hypertension and heart disease. Yet, instead, we allow our health to deteriorate and then rush to modern medicine to seek “cures” or at least treatments for the outcomes of our bad habits.

I suspect that this trap of habits was set for us, to some degree, by the brilliant innovation and success of antibiotics.  These are the quintessential medical cures:  When used against an infection caused by a sensitive bacteria, antibiotics actually CURE the problem (with the help of our own immune system).  To some degree anti-virals do the same, though they are more recent, and anti-parasitic agents are also analogous.

Unfortunately, most other kinds of medicines–unless you count the occasional Tylenol or Motrin to treat a tension headache or muscle soreness–don’t actually cure anything.  They simply “treat” it, governing the symptoms and consequences to some degree or other, but not addressing whatever underlying processes might be contributing to the issues.  In addition, they give the patient the illusion that the problem is now under real control.

There are, of course, times, when health problems are not soluble or easily controllable, and managing the symptoms and consequences is the very best we can do, at least for now.  So PLEASE do not think that I am advocating the elimination of Western medicine or that those being treated for chronic health conditions should just give up their pills and let nature take its course.  Yet with so many health problems, even if we have to resort to medication, we can also make lifestyle and behavioral changes that will mitigate our problems and decrease, though not always eliminate, the need for medications (and surgery, when applicable).

We all know, or should know, that taking medicine can be a double-edged sword.  Medications sometimes create new issues of their own.  The human body is an incredibly complex system–arguably the most complicated thing in the known universe, especially when you count the human brain–and when you manipulate such a  system in one way or location, unexpected consequences almost never fail to arise.  This leads to the horrible spectacle of patients receiving medication for one problem, but developing side-effects, which then need to be treated by other medications, and which cause toxicities and interactions that later have to be addressed.  The whole affair can become a vicious cycle of increasing biological chaos, like a metabolic Rube Goldberg machine.  In the elderly especially, it can sometimes be all but impossible to be certain whether new health problems are intrinsic or are caused by earlier treatments.

We try, of course, to mitigate and avoid this conundrum by studying medications as carefully as possible and learning what their possible side-effects are…but every human body is different, and that’s going to continue to be the case, since the number of possible genetically unique humans is vastly greater than the number of human beings who have ever lived.  So we can be guaranteed that the one expectation we can reliably entertain is the UNEXPECTED.

It is better by far to avoid developing problems whenever possible rather than trying to treat them.  This is true because it is simpler and more predictable, and also because it makes life better.  Rather than being a person who identifies themselves by their litany of ailments, for which they build their house-of-cards treatment regimens, we can work to maintain lifestyles that are GOOD for our health, that work with our natures, and that help us to think of ourselves as–and to feel like–healthy, vital and thriving human beings.

Medicines are indeed wonderful products of modern science and technology, and I strongly suspect that they have saved and improved many more lives than they have harmed, even despite what I’ve said above.  If I didn’t think that, I wouldn’t have gone into medicine.  Yet, it would be even better if we could avoid having the need for medications as often as possible in the first place.

I’m going to discussing more of this in future entries.  I’ll go into some fairly obvious lifestyle issues such as exercise and diet, but I’m also going to explore philosophical and psychological aspects of health that can make a great difference in not only how long you live, but also in how much you enjoy the time you have.

A life of a hundred years can be a tragedy and a life of a single day can be a triumph.  It all depends on what kind of life it is.
